2.8 Calculating Power Requirements
Table 1: Milliamp Consumption Table
STEP 1: Using Table 1, calculate the total number of milliamps (mA) required by each device, module, and accessory in the
system. Please take into account devices connected to the control panel’s PGM outputs. Since the
BELL output has
its own power supply, do not include the sirens connected to it in the calculation.
STEP 2:
If the Grand Total is less than 700mA, go to step 3. If the value is greater, you will require an external power supply (see
Figure 5 on page 5) to provide the additional power needed. Proceed with step 3 and refer to the example in Figure 4 on
page 5.
STEP 3: Due to the degradation of a power signal over long distances, EACH length or run of wire in the system can
support only a specific number of milliamps (mA). Using Table 2, determine how many milliamps each length of
wire can support. Please note that the total number of milliamps (mA) can never surpass 700mA.
